تایید سن از طولانی ترین انسان زنده در جهان است

We collected official documents, and non-official records to check face validity. We also gathered life episodes told by J.K. and historical records to evaluate concurrent validity. Although we found several date inconsistencies among documents and mismatches between told episodes and actual dates of events, no critical discordances were discovered. In conclusion, we could verify that J.K. was born on April 19, 1897 and passed away on June 12, 2013 at the age of 116 years and 54 days.
